The sixth frequency moments for an anisotropic paramagnet with exchange-bond dilution

The sixth frequency moments of the spin correlation function for a bond-diluted anisotropic Heisenberg paramagnet in the high temperature limit are evaluated for arbitrary spin values. Results for both the transverse and longitudinal moments are presented for a model in which the transverse and longitudinal exchange bonds can fluctuate independently. The results are presented in a form which allows the moments for the undiluted, site diluted, and single-bond diluted moments to be also written down.
